From a single entry point in the pipeline, PanaFlow MV meters offer precise measurements of mass or volumetric flow. The velocity sensor reduces the effects of pipeline vibration by incorporating a unique piezoelectric element that senses the vortex frequency. To extend range-ability at the low end of flow, the meter's smart electronics calculates the Reynolds number (Re) based on constant values of fluid density and viscosity stored in memory, and automatically corrects for any non-linearity down to Re = 5,000. PanaFlow MV digital electronics allows reconfiguration for most gases, liquids and steam. The instrument is loop powered (12 to 36 VDC) with two output signals. The pulse output signal is proportional to volumetric flow rate; the analog linear 4-20 mA signal offers your choice of volumetric flow rate or mass flow rate. The mass flow rate is based on a constant value for fluid density stored in the instrument's memory. The local key-pad/display provides instantaneous flow rate in engineering units or to-talized flow. Operating the PanaFlow MV FLOW Figure 1-1: In-Line Vortex Multi-Parameter Mass Flowmeter The Series MV80 and MV82 PanaFlow MV Vortex Flowmeters use a unique velocity sensor head to monitor volumetric flow rate. The built-in flow computer calculates mass flow rate based on a constant value of fluid density stored in the instrument's memory. To measure fluid velocity, the flow meter incorporates a bluff body (shedder bar) in the flow stream, and the velocity sensor measures the frequency of vortices cre-ated by the shedder bar. The velocity sensor head is located downstream of the shedder bar within the flow body. Introduction 1-1 June 2007 Velocity Measurement The PanaFlow MV vortex velocity sensor is a patented mechanical design that minimizes the effects of pipeline vibration and pump noise, both of which are common error sources in flow measurement with vortex flowmeters. The velocity measurement is based on the well-known Von Karman vortex shedding phenomenon. Vortices are shed from a shedder bar, and the vortex velocity sensor located downstream of the shedder bar senses the passage of these vortices. This method of velocity measurement has many advantages including inherent linearity, high turndown, reliability and simplicity. Vortex Shedding Frequency Von Karman vortices form downstream of a shedder bar into two distinct wakes. The vortices of one wake rotate clockwise while those of the other wake rotate counterclockwise. Vortices generate one at a time, alternating from the left side to the right side of the shedder bar. Vortices interact with their surrounding space by over-powering every other nearby swirl on the verge of development. Close to the shedder bar, the distance (or wave length) between vortices is always constant and measurable. Therefore, the volume encompassed by each vortex remains constant, as shown below. By sensing the number of vortices passing by the velocity sensor, the PanaFlow MV Vortex Flowmeter computes the total fluid volume. Velocity Sensor Vortex Shedder Bar Vortices Flow Constant Wave Length Figure 1-2: Measurement Principle of Vortex Flowmeters 1-2 Introduction June 2007 Vortex Frequency Sensing The velocity sensor incorporates a piezoelectric element that senses the vortex frequency. This element detects the alternating lift forces produced by the Von Karman vortices flowing downstream of the vortex shedder bar. The alternating electric charge generated by the piezoelectric element is processed by the transmitter’s electronic circuit to obtain the vortex shedding frequency. The piezoelectric element is highly sensitive and operates over a wide range of flows, pressures and temperatures. Flow Velocity Range To ensure trouble-free operation, vortex flowmeters must be correctly sized so that the flow velocity range through the meter lies within the measurable velocity range (with acceptable pressure drop) and the linear range. The measurable range is defined by the minimum and maximum velocity using the following table. Table 1-1: Measurable Ranges Gas Liquid Vmin 25ft/s --------------r 1 ft/s Vmax 300 ft/s 30 ft/s Vmin 37m/s ---------------r 0.3 m/s Vmax 91 m/s 9.1 m/s English r (lb/ft3) Metric r (kg/m3) The pressure drop for series MV82 insertion meters is negligible. The pressure drop for series MV80 in-line meters is defined as: ΔP = .00024 r V2 English units (ΔP in psi, r in lb/ft3, V in ft/sec) ΔP = .000011 r V2 Metric units (ΔP in bar, r in kg/m3, V in m/sec) The linear range is defined by the Reynolds number. The Reynolds number is the ratio of the inertial forces to the viscous forces in a flowing fluid and is defined as: Re = ρVD ---------μ Where: Re = Reynolds Number r = mass density of the fluid being measured V = velocity of the fluid being measured D = internal diameter of the flow channel µ = viscosity of the fluid being measured Introduction 1-3 June 2007 Flow Velocity Range (cont.) The Strouhal number is the other dimensionless number that quantifies the vortex phenomenon. The Strouhal number is defined as: fd St = ----V Where: St = Strouhal Number f = frequency of vortex shedding d = shedder bar width V = fluid velocity As shown in Figure 1-3 below, PanaFlow MV meters exhibit a constant Strouhal number across a large range of Reynolds numbers, indicating a consistent linear output over a wide range of flows and fluid types. Below this linear range, the intelligent electronics in PanaFlow MV automatically corrects for the variation in the Strouhal number. PanaFlow MV's smart electronics correct for this nonlinearity by calculating the Reynolds number based on constant values of the fluid's density and viscosity stored in the instrument's memory. PanaFlow MV Vortex Flowmeters automatically correct down to a Reynolds number of 5,000. Strouhal Number, St Corrected Range 0.3 Linear Range 0.2 0.1 0.0 10 3 10 4 5000 10 5 10 6 10 7 10 8 Reynolds Number, Re Figure 1-3: Reynolds Number Range for the PanaFlow MV 1-4 Introduction June 2007 Flowmeter Configurations PanaFlow MV Vortex Flowmeters are available in two configurations: • Model MV80 in-line flowmeter (replaces a section of the pipeline) • Model MV82 insertion flowmeter (requires a “cold” tap or a “hot” tap into an existing pipeline) The in-line and insertion configurations are similar in that they use identical electronics and have similar sensor heads. Besides installation differences, the main difference between an in-line flowmeter and an insertion flowmeter is their method of measurement. For an in-line vortex flowmeter, the shedder bar is located across the entire diameter of the flow body. Thus, the entire pipeline flow is included in the vortex formation and measurement. The sensing head, which directly measures velocity, temperature and pressure is located just downstream of the shedder bar. An insertion vortex flow meter has its sensing head at the end of a 0.750 inch diameter tubular stem. The stem is inserted into the pipe until the sensing head is properly located in the pipe's cross section. The sensing head fits through any entry port with an 1.875 inch minimum internal di-ameter. The sensing head of an insertion vortex flow meter directly monitors the velocity at a point in the cross-sectional area of a pipe, duct, or stack (re-ferred to as "channels"). The velocity at a point in the pipe varies as a function of the Reynolds number. The insertion vortex flow meter com-putes the Reynolds number based on constant values of the fluid's density and viscosity stored in its memory and then computes the total flow rate in the channel. The output signal of insertion meters is the total flow rate in the channel. The accuracy of the total flow rate computation depends on adherence to the piping installation requirements given in Chapter 2. If adherence to those guidelines cannot be met, contact the factory for specific installation advice. Introduction 1-5 June 2007 Flowmeter Electronics PanaFlow MV Flowmeter electronics are available mounted directly to the flow body, or remotely mounted. The electronics housing may be used indoors or outdoors, including wet environments. The instrument requires 4-20 mA loop power (12 to 36 VDC). One analog output signal is available for your choice of volumetric flow rate or mass flow rate. A pulse output is available for totalization. The meter includes a local 2 x 16 character LCD display housed within the enclosure. Local operation and reconfiguration is accomplished using six push buttons. For hazardous locations, the six push buttons can be operated through the sealed enclosure using a hand-held magnet, thereby not compromising the integrity of the hazardous location certifi-cation. The electronics include nonvolatile memory that stores all configuration information. The memory allows the flowmeter to function immediately upon power up, or after an interruption in power. 1-6 Introduction Chapter 2 Installation Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-1 Series MV80 In-Line Flowmeter Installation. . . . . . . . . . . . . . . . . . . . . . . . 2-3 Series MV82 Insertion Flowmeter Installation. . . . . . . . . . . . . . . . . . . . . . 2-8 Flowmeter Insertion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-12 Adjusting Meter Orientation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-21 Wiring Connections . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-23 June 2007 Overview The PanaFlow MV Flowmeter installations are simple and straightforward. Both the Series MV80 In-Line and Series MV82 Insertion type flowmeter installations are covered in this chapter. After reviewing the installation requirements given below, see page 2-3 for Series MV80 Installation instructions. See page 2-8 for Series MV82 Installation instructions. Wiring instructions begin on page 2-23. Flowmeter Installation Requirements Caution! Consult the flowmeter nameplate for specific flowmeter approvals before any hazardous location installation. Before installing the flowmeter, verify that the installation site allows for these considerations: 1. Line pressure and temperature will not exceed the flowmeter rating. 2. The location meets the required minimum number of pipe diameters upstream and downstream of the sensor head as illustrated in Figure 2-1 on page 2-2. 3. There is safe and convenient access with adequate overhead clearance for maintenance purposes. 4. The cable entry into the instrument meets the specific standard required for hazardous area installations. 5. For remote installations, the supplied cable length is sufficient to connect the flowmeter sensor to the remote electronics. Also, before installation, check the flow system for anomalies such as: Installation • leaks • valves or restrictions in the flow path that could create disturbances in the flow profile that might cause unexpected flow rate indications 2-1 June 2007 Unobstructed Flow Requirements Select an installation site that will minimize possible distortion in the flow profile. Valves, elbows, control valves and other piping components may cause flow disturbances. Check your specific piping condition against the examples shown below. In order to achieve accurate and repeatable performance, install the flowmeter using the recommended number of straight run pipe diameters upstream and downstream of the sensor. Note: For liquid applications in vertical pipes, avoid installing with flow in the downward direction because the pipe may not be full at all points. Choose to install the meter with flow in the upward direction if possible. A B Flow meter Example 1. One 90° elbow before meter A C' C B A C' Flow meter Flow conditioner (if used) Example 4.

Recommended Pipe Length Requirements for Installation, Series M22 and M23 Figure 2-1: Recommended Pipe Length Requirements for Installation - Series MV80 & MV82 2-2 Installation June 2007 Series MV80 In-Line Flowmeter Installation Install the Series MV80 In-Line Flowmeter between two conventional pipe flanges as shown in Figure 2-3 on page 2-4 and Figure 2-4 on page 2-6. Table 2-1 below provides the recommended minimum stud bolt lengths for wafer-style meter body size and different flange ratings. The meter inside diameter is equal to the same size nominal pipe ID in schedule 80. For example, a 2” meter has an ID of 1.939” (2” schedule 80). Do not install the meter in a pipe with an inside diameter smaller than the inside diameter of the meter. For schedule 160 and higher pipe, a special meter is required. Consult the factory before purchasing the meter. Series MV80 Meters require customer-supplied gaskets. When selecting gasket material make sure that it is compatible with the process fluid and pressure ratings of the specific installation. Verify that the inside diameter of the gasket is larger than the inside diameter of the flowmeter and adjacent piping. If the gasket material extends into the flow stream, it will disturb the flow and cause inaccurate measurements.

If the process fluid is a liquid, make sure the meter is located where the pipe is always full. This may require locating the meter at a low point in the piping system. Note: Vortex flowmeters are not suitable for two-phase flows (i.e., liquid and gas mixtures). For horizontal pipelines having a process temperature above 300° F, mount the meter at a 45° or 90° angle to avoid overheating the electronics enclosure. To adjust the viewing angle of the enclosure or display/keypad, see Display/Keypad Adjustment on page 2-22. Enclosure and display/keypad are adjustable to suit most viewing angles. Shedder bar (bluff body) is positioned upstream of the sensor. Incorrect gasket position! Do not allow any gasket material to extend into the flow profile. FLOW Figure 2-3: Wafer-Style Flowmeter Installation Caution! When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow before installing the flowmeter. When installing the meter make sure the section marked “inlet” is positioned upstream of the outlet, facing the flow. This ensures that the sensor head is positioned downstream of the vortex shedder bar and is correctly aligned to the flow. Installing the meter opposite this direction will result in completely inaccurate flow measurement. 2-4 Installation June 2007 Wafer-Style Flowmeter (cont.) To install the meter: 1. Turn off the flow of process gas, liquid or steam. Verify that the line is not pressurized. Confirm that the installation site meets the required minimum upstream and downstream pipe diameters. 2. Insert the studs for the bottom side of the meter body between the pipe flanges. Place the wafer-style meter body between the flanges with the end stamped “inlet” facing flow. Center the meter body inside the diameter with respect to the inside diameter of the adjoining piping. 3. Position the gasket material between the mating surfaces. Make sure both gaskets are smooth and even with no gasket material extending into the flow profile. Obstructions in the pipeline will disturb the flow and cause inaccurate measurements 4. Place the remaining studs between the pipe flanges. Tighten the nuts in the sequence shown in Figure 2-2 on page 2-3. Check for leaks after tightening the flange bolts. Installation 2-5 June 2007 Flange-Style Flowmeter Install the flange-style meter between two conventional pipe flanges of the same nominal size as the flowmeter. If the process fluid is a liquid, make sure the meter is located where the pipe is always full. This may require locating the meter at a low point in the piping system. Note: Vortex flowmeters are not suitable for two-phase flows (i.e., liquid and gas mixtures). For horizontal pipelines having a process temperature above 300° F, mount the meter at a 45° or 90° angle to avoid overheating the electronics enclosure.

FLOW Figure 2-4: Flange-Style Flowmeter Installation Caution! When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow before installing the flowmeter. When installing the meter make sure the flange marked “inlet” is positioned upstream of the outlet flange, facing the flow. This ensures that the sensor head is positioned downstream of the vortex shedder bar and is correctly aligned to the flow. Installing the meter opposite this direction will result in completely inaccurate flow measurement. 2-6 Installation June 2007 Flange-Style Flowmeter (cont.) To install the meter: 1. Turn off the flow of process gas, liquid or steam. Verify that the line is not pressurized. Confirm that the installation site meets the required minimum upstream and downstream pipe diameters. 2. Seat the meter level and square on the mating connections with the flange marked “inlet” facing the flow. Position a gasket in place for each side. Make sure both gaskets are smooth and even with no gasket material extending into the flow profile. Obstructions in the pipeline will disturb the flow and cause inaccurate measurements. 3. Install bolts in both process connections. Tighten the nuts in the sequence shown in Figure 2-2 on page 2-3. Check for leaks after tightening the flange bolts. Installation 2-7 June 2007 Series MV82 Insertion Flowmeter Installation Prepare the pipeline for installation using either a cold tap or hot tap method described on the following pages. Refer to a standard code for all pipe tapping operations. The following tapping instructions are general in nature and intended for guideline purposes only. Before installing the meter, review the mounting position and isolation value requirements given below. Mounting Position Allow clearance between the electronics enclosure top and any other obstruction when the meter is fully retracted. Isolation Valve Selection An isolation valve is available as an option with Series MV82 meters. If you supply the isolation valve, it must meet the following requirements: 1. A minimum valve bore diameter of 1.875 inches is required, and the valve’s body size should be two inches. Normally, gate valves are used. 2. Verify that the valve’s body and flange rating are within the flowmeter’s maximum operating pressure and temperature. 1.875-inch min. valve bore 2-inch min. 2-inch valve size Isolation Valve Requirements 3. Choose an isolation valve with at least two inches existing between the flange face and the gate portion of the valve. This ensures that the flowmeter’s sensor head will not interfere with the operation of the isolation valve. 2-8 Installation June 2007 Cold Tap Guidelines Refer to a standard code for all pipe tapping operations. Caution! When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow before installing the flowmeter. !WARNING! All flowmeter connections, isolation valves and fittings for cold tapping must have the same as or higher pressure rating than the main pipeline. The following tapping instructions are general in nature and intended for guideline purposes only. 1. Turn off the flow of process gas, liquid or steam. Verify that the line is not pressurized. 2. Confirm that the installation site meets the minimum upstream and downstream pipe diameter requirements (see Figure 2-1 on page 2-2). 3. Use a cutting torch or sharp cutting tool to tap into the pipe. The pipe opening must be at least 1.875 inches in diameter. (Do not attempt to insert the sensor probe through a smaller hole.) 4. Remove all burrs from the tap. Rough edges may cause flow profile distortions that could affect flowmeter accuracy. Also, obstructions could damage the sensor assembly when inserting into the pipe. 5. After cutting, measure the thickness of the cut-out and record this number for calculating the insertion depth. 6. Weld the flowmeter pipe connection on the pipe. Make sure this connection is perpendicular to the pipe centerline within ± 5°. 7. Install the isolation valve (if used). 8. When welding is complete and all fittings are installed, close the isolation valve or cap the line. Run a static pressure check on the welds. If pressure loss or leaks are detected, repair the joint and retest. 9. Connect the meter to the pipe process connection. 10.Calculate the sensor probe insertion depth as described on the following pages. Insert the sensor probe into the pipe. Installation 2-9 June 2007 Hot Tap Guidelines Refer to a standard code for all pipe tapping operations. !WARNING! Hot tapping must be performed by a trained professional. U.S. regulations often require a hot tap permit. The manufacturer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a permit. !WARNING! All flowmeter connections, isolation valves and fittings for hot tapping must have the same as or higher pressure rating than the main pipeline. The following tapping instructions are general in nature and intended for guideline purposes only. 1. Confirm that the installation site meets the minimum upstream and downstream pipe diameter requirements. 2. Weld a two inch mounting adapter on the pipe. Make sure the mounting adapter is within ± 5° perpendicular to the pipe centerline (see page 2-9). The pipe opening must be at least 1.875 inches in diameter. 3. Connect a two inch process connection on the mounting adapter. 4. Connect an isolation valve on the process connection. The valve’s full open bore must be at least 1.875 inches in diameter. 5. Hot tap the pipe. 6. Close the isolation valve. Run a static pressure check on the welds. If pressure loss or leaks are detected, repair the joint and re-test. 7. Connect the flowmeter to the isolation valve. 8. Calculate the sensor probe insertion depth as described on the following pages. Insert the sensor probe assembly into the pipe. 2-10 Installation June 2007 Check upstream and downstream piping requirements. Weld mounting adapter. Connect process connection (flange or NPT) Connect isolation valve. Hot tap pipe FLOW Test for leaks, purge pipe. Connect meter to valve, calculate insertion depth, install flowmeter. Figure 2-5: Hot Tap Sequence Installation 2-11 June 2007 Flowmeter Insertion The sensor head must be properly positioned in the pipe. For this reason, it is important that insertion length calculations are carefully followed. A sensor probe inserted at the wrong depth in the pipe will result in inaccurate readings. Insertion flowmeters are applicable to pipes 2 inch and larger. For pipe sizes ten inches and smaller, the centerline of the meter’s sensing head is located at the pipe’s centerline. For pipe sizes larger than ten inches, the centerline of the sensing head is located in the pipe’s cross section five inches from the inner wall of the pipe; i.e., its “wetted” depth from the wall to the centerline of the sensing head is five inches. Insertion flowmeters are available in three probe lengths: Use the Correct Insertion Formula • Standard Probe configuration is used with most flowmeter process connections. The length, S, of the stem is 29.47 inches. • Compact Probe configuration is used with compression fitting process connections. The length, S, of the stem is 13.1 inches. • 12-Inch Extended Probe configuration is used with exceptionally lengthy flowmeter process connections. The length, S, of the stem is 41.47 inches. Depending on the flowmeter’s process connection, use the applicable insertion length formula and installation procedure as follows: • For flowmeters with a compression type connection (NPT or flanged), follow the instructions beginning on page 2-13. • For flowmeters with a packing gland type connection (NPT or flanged) configured with an insertion tool, follow the instructions beginning on page 2-16. • For flowmeters with a packing gland type connection (NPT or flanged) without an insertion tool, follow the instructions beginning on page 2-20. !WARNING! An insertion tool must be used for any installation where a flowmeter is inserted under pressure greater than 50 psig. 2-12 Installation June 2007 Installation with a Compression Connection* Use the following formula to determine insertion length for flowmeters (NPT and flanged) with a compression process connection. The installation procedure is given on page 2-15. Insertion Length Formula I =S–F–R–t Where: I = Insertion length. S= Stem length – the distance from the center of the sensor head to the base of the enclosure adapter (S = 29.47 inches for standard probes; S = 13.1 inches for compact; S = 41.47 inches for 12-inch extended). F= Distance from the raised face of the flange or top of NPT stem housing to the outside of the pipe wall. R= Pipe inside diameter y 2 for pipes ten inches and smaller. R= Five inches for pipe diameters larger than ten inches. t = Thickness of the pipe wall. (Measure the disk cut-out from the tapping procedure or check a piping handbook for thickness.) Figure 2-6: Insertion Calculation (Compression Type) Example: To install a Series MV82 meter with a standard probe (S = 29.47 in.) into a 14 inch schedule 40 pipe, the following measurements are taken: F = 3 inches; R = 5 inches; t = 0.438 inches The insertion length for this example is 21.03 inches. Insert the stem through the fitting until an insertion length of 21.03 inches is measured with a ruler. *All dimensions are in inches. Installation 2-13 June 2007 Installation with a Compression Connection (cont.) Caution! The sensor alignment pointer must point downstream, in the direction of the flow. !WARNING! To avoid serious injury, DO NOT loosen the compression fitting under pressure. Figure 2-7: Flowmeter with a Compression Type Fitting 2-14 Installation June 2007 Installation with a Compression Connection (cont.) 1. Calculate the required sensor probe insertion length. 2. Fully retract the stem until the sensor head is touching the bottom of the stem housing. Slightly tighten the compression nut to prevent slippage. 3. Bolt or screw the flowmeter assembly into the process connection. 4. Use PTFE tape or pipe sealant to improve the seal and prevent seizing on NPT styles. 5. Hold the meter securely while loosening the compression fitting. Insert the sensor into the pipe until the calculated insertion length, I, is measured between the base of the enclosure adapter and the top of the stem housing, or to the raised face of the flanged version. Do not force the stem into the pipe. 6. Align the sensor head using the sensor alignment pointer. Adjust the alignment pointer parallel to the pipe and pointing downstream. 7. Tighten the compression fitting to lock the stem in position. When the compression fitting is tightened, the position is permanent. Installation 2-15 June 2007 Installation with a Packing Gland Connection* Use the formula below to determine the insertion depth for flowmeters (NPT and flanged) equipped with an insertion tool. To install, see page 2-17 for instructions for meters with a permanent insertion tool. For meters with a removable insertion tool, see page 2-18. Insertion Length Formula I = F + R + t – 1.35 Where: I = Insertion length. F = Distance from the raised face of the flange or top of the process connection for NPT style meters to the top outside of the process pipe. R = Pipe inside diameter y 2 for pipes ten inches & smaller. R = Five inches for pipe diameters larger than ten inches. t = Thickness of the pipe wall. (Measure the disk cut-out from the tapping procedure or check a piping handbook for thickness.) Figure 2-8: Insertion Calculation (Meters with Insertion Tool) Example 1: Flange Style Meters: To install a Series MV82 Flowmeter into a 14 inch schedule 40 pipe, the following measurements are taken: F = 12 inches; R = 5 inches; t = 0.438 inches The example insertion length is 16.09 inches. Example 2: NPT Style Meters: The length of thread engagement on the NPT style meters is also subtracted in the equation. The length of the threaded portion of the NPT meter is 1.18 inches. Measure the thread portion still showing after the installation and subtract that amount from 1.18 inches. This gives you the thread engagement length. If this cannot be measured use .55 inch for this amount. F = 12 inches; R = 5 inches; t = 0.438 inches The example insertion length is 15.54 inches. *All dimensions are in inches. 2-16 Installation June 2007 Insertion Procedure for Flowmeters with Permanent Insertion Tool Figure 2-9: Flowmeter with Permanent Insertion Tool Caution!

To avoid potential electric shock, follow National Electric Code safety practices or your local code when wiring this unit to a power source and to peripheral devices. Failure to do so could result in injury or death. All wiring procedures must be performed with the power off. 2-23 June 2007 Wiring Connections (cont.) The NEMA 4X enclosure contains an integral wiring compartment with one dual strip terminal block (located in the smaller end of the enclosure). Two 3/4-inch female NPT conduit entries are available for separate power and signal wiring. For all hazardous area installations, make sure to use an agency-approved fitting at each conduit entry. If conduit seals are used, they must be installed within 18 inches (457 mm) of the enclosure. Loop Pulse Power Output Power + – + – + – Figure 2-14: Pulse and Power Terminals Input Power Connections To access the wiring terminal blocks, locate and loosen the small set screw which locks the small enclosure cover in place. Unscrew the cover to expose the terminal block. DC Power Wiring Connect 4-20 mA loop power (12-36 VDC) to the +Pwr and –Pwr terminals on the terminal block. Torque all connections to 4.43-5.31 in-lbs (0.5-0.6 Nm). The DC power wire size must be 20-10 AWG with the wire stripped 1/2 inch (14 mm). The nominal voltage required to operate the 4-20 mA loop is 12 volts at the meter. The 4-20 mA loop is optically isolated from the flow meter electronics. RLoad 12 to 36 VDC + Pwr – Pwr Figure 2-15: DC Power Connections 2-24 Installation June 2007 4-20mA Output Connections The standard PanaFlow MV Flowmeter has a single 4-20 mA loop. The 4-20 mA loop current is controlled by the meter electronics. The electronics must be wired in series with the sense resistor or current meter. The current control electronics require 12 volts at the input terminals to operate correctly. The maximum loop resistance (load) for the current loop output is dependent upon the supply voltage and is given in Figure 2-16. The 4-20 mA loop is optically isolated from the flowmeter electronics. Rload is the total resistance in the loop, including the wiring resistance (Rload = Rwire + Rsense). To calculate Rmax, the maximum Rload for the loop, use the maximum loop current, 20 mA. The voltage drop in the loop due to resistance is 20 mA times Rload and this drop is subtracted from the input voltage. Thus: The maximum resistance Rload = Rmax = 50 X (Vsupply – 12V).

When the preset volume or mass (defined in the totalizer settings, see page 3-6) has passed the meter, the output provides a 50 millisecond square pulse. The pulse output requires a separate 5 to 36 VDC power supply. The pulse output optical relay is a normally-open single-pole relay. The relay has a nominal 200 volt/160 ohm rating. This means that it has a nominal on-resistance of 160 ohms, and the largest voltage that it can withstand across the output terminals is 200 volts. However, there are current and power specifications that must be observed. The relay can conduct a current up to 40 mA and can dissipate up to 320 mW.

The sections in this chapter explain the display/ keypad commands, meter start-up and programming. The meter is ready to operate at start up without any special programming. To enter parameters and system settings unique to your operation, see the following pages for instructions on using the setup menus. Display/Keypad The flowmeter’s digital electronics enable you to set, adjust and monitor system parameters and performance. A full range of commands is available through the display/keypad. The LCD display gives 2 x 16 characters for flow monitoring and programming. The six push buttons can be operated with the enclosure cover removed. Or, the explosion-proof cover can remain in place and the keypad operated with a hand-held magnet positioned at the side of the enclosure as shown in the illustration at the left. From the Run Mode, the ENTER key enables access to the Setup Menus (through a password screen). Within the Setup Menus, pressing ENTER activates the current field. To set new parameters, press the ENTER key until an underline cursor appears. Use the keys to select new parameters. Press ENTER to continue. (If change is not allowed, ENTER has no effect.) All outputs are disabled when using the Setup Menus. The EXIT key is active within the Setup Menus. When using a Setup Menu, EXIT returns you to the Run Mode. If you are changing a parameter and make a mistake, EXIT enables you to start over. The keys advance through each screen of the current menu. When changing a system parameter, all keys are available to enter new parameters. Figure 3-1: Flowmeter Display/Keypad Operation 3-1 June 2007 Startup To begin flowmeter operation: 1. Verify the flowmeter is installed and wired as described in Chapter 2. 2. Apply power to the meter. At start up, the unit runs a series of selftests that check the RAM, ROM, EPROM and all flow sensing components. After completing the self-test sequence, the Run Mode screens appear (see figure below). Note: Starting the flowmeter or pressing EXIT will always display the Run Mode screens. 3.

YES or NO Example: Maximum flowrate = 600 gallons per minute (600 gallons per minute = 10 gallons per second) If unit per pulse is set to 600 gallons per pulse, the totalizer will pulse once every minute. If unit per pulse is set to 10 gallons per pulse, the totalizer will pulse once every second. Use the Totalizer Menu to configure and monitor the totalizer. The totalizer output is a 50 millisecond (.05 second) positive pulse (relay closed for 50 milliseconds). The totalizer cannot operate faster than one pulse every 100 millisecond (.1 second). A good rule to follow is to set the unit per pulse value equal to the maximum flow in the same units per second. This will limit the pulse to no faster than one pulse every second. Example for Setting the Totalizer The following sets the totalizer to track volumetric total gallons. Note: All outputs are disabled while using the Setup Menus.

Troubleshooting and Repair 5-1 June 2007 Column One Hidden Diagnostics Values Table 5-1: Column One Hidden Diagnostic Values Description f Vortex shedding frequency (Hz). If an asterisk (*) is displayed after the f value, a valid vortex signal is being registered for the flow. fi Adaptive filter – Should be approximately 25% higher than the vortex shedding frequency. This is a low-pass filter. Note: If the meter is using the Filter Control (see below) in the manual mode, fi will be displayed as fm. G Gain (applied to vortex signal amplitude). Gain defaults to 1.0 and can be changed using the Gain Control (see below). A Amplitude of vortex signal in Volts rms. A1, A2, A3, A4 Kc, It, Kb A/D counts representing the vortex signal amplitude. Each stage (A1-A4) cannot exceed 512. Beginning with stage A1, the A/D counts increase as the flow increases. When stage A1 reaches 512, it will shift to stage A2. This will continue as the flow rate increases until all 4 stages read 512 at high flow rates. Higher flow rates (stronger signal strength) will result in more stages at 512. Profile equation (factory use only). Series 221 only. V Calculated average pipe velocity (ft/sec). Re Calculated Reynolds number. Ck Lvl Adj. Filter O,I Calculated Ck at current operating conditions. Ck is a variable in the equation that relates signal strength, density, and velocity for a given application. It is used for noise rejection purposes. Ck directly controls the fi value (see above). If the Ck is set too low (in the calibration menu), then the fi value will be too low and the vortex signal will be rejected resulting in zero flow rate being displayed. The calculated Ck valun in this menu can be compared to the actual Ck setting in the calibration menu to help determine if the Ck setting is correct. Threshold level. If the Low Flow Cutoff in the calibration menu is set above this value, the meter will read zero flow. The Lvl level can be checked at no flow. At no flow, the Lvl must be below the Low Flow Cutoff setting or the meter will have an output at no flow Adjustable filter. Displays filtering in decibels. Normally reads zero. If value is consitently –5 or –10, for example, the Ck or density setting may be wrong. Factory use only. Pulse output queue. This value will accumulate if the totalizer is accumulating faster than the pulse output hardware can function. The queue will allow the Pulse Out Queue pulses to "catch up" later if the flow rate decreases. A better practice is to slow down the totalizer pulse by increasing the value in the (unit)/pulse setting in the totalizer menu. TOF, G, f Factory use only. Sig.

Gain Control Manual gain control (factory use only). Leave set at 1.0. Filter Control Manual filter control. This value can be changed to any number to force the fi value to a constant. A value of zero activates the automatic filter control which sets fi at a level that floats above the f value. Reset to factory defaults. If you change this to YES and press ENTER, all factory Factory Defaults configuration is lost and you must reconfigure the entire program. Consult the factory before performing this process. It is required only in very rare cases. Meter Type Test Pulse Out Insertion (Model MV82) or Inline (Model MV80) meter. Force totalizer pulse. Set to YES and press ENTER to send one pulse. Very useful to test totalizer counting equipment. Analog Output Calibration To check the 4–20 mA circuit, connect a DVM in series with the output loop. Select zero or full scale (from the second column of the hidden diagnostics) and then actuate the ENTER key twice. This action will cause the meter to output its 4 mA or 20 mA condition. If the DVM indicates a current greater than ± 0.006 mA from 4 or 20, adjust the setting up or down until the output is calibrated. Note: These settings are not for adjusting the output zero and span to match a flow range. That function is located in the Output Menu. Troubleshooting the Flowmeter Symptom: Output at no Flow The low flow cutoff is set too low. At no flow, go to the first column of the hidden diagnostics menu and record the Lvl value. The low flow cutoff must be set above this value. Example: At no flow, Lvl = 25. Set the low flow cutoff in the Calibration Menu to approximately 28 and the meter will no longer read a flow rate at no flow. Troubleshooting and Repair 5-3 June 2007 Symptom: Erratic Output 1. The flow rate may be too low, just at the cutoff of the meter range, and the flow cycles above and below the cutoff making an erratic output. The meter range is stamped on the label on the outside of the electronics enclosure cover (based on application conditions when the meter was ordered). Consult the factory if necessary to confirm the meter range based on current operating conditions. It may be possible to lower the low flow cutoff to increase the meter range. See the example above for output at no flow, only this time the low flow cutoff is set too high. You can lower this value to increase the meter range as long as you do not create the output at no flow condition previously described. 2. Mechanical installation may be incorrect. Verify the straight run is adequate as described in Chapter 2. For in-line meters, make sure the meter is not installed backwards and there are no gaskets protruding into the flow stream. For insertion meters, verify the insertion depth and flow direction. 3. The meter may be reacting to actual changes in the flow stream. The output can be smoothed using a time constant. The displayed values can be smoothed using the time constant in the Display Menu. The analog outputs can be smoothed using the time constant in the Output Menu. A time constant of 1 will result in the change in value reaching 63% of its final value in one second. A time constant of 4 is 22%, 10 is 9.5% and 50 is 1.9% of the final value in one second. The time constant equation is shown below (TC = Time Constant). % change to final value in one second = 100 (1 – e(-1/TC)) 4. The vortex coefficient Ck may be incorrectly set. The Ck is a value in the equation used to determine if a frequency represents a valid vortex signal given the fluid density and signal amplitude. In practice, the Ck value controls the adaptive filter, fi, setting. During flow, view the f and fi values in the first column of the hidden diagnostics. The fi value should be approximately 10-20 % higher than the f value. If you raise the Ck setting in the Calibration Menu, then the fi value will increase. The fi is a low pass filter, so by increasing it or lowering it, you can alter the range of frequencies that the meter will accept. If the vortex signal is strong, the fi value will increase to a large number – this is correct. 5-4 Troubleshooting and Repair June 2007 Symptom: No Output 1. For remote mounted electronics, carefully check all the wiring connections in the remote mount junction box. There are six connections that must be correct. Verify each color (black and red), shield, and wire number. 2. Check the density value in the Calibration Menu to see if it is correct for the current operating conditions. 3. Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover. Disconnect the vortex sensor from the Signal board. Measure the resistance from each Sensor pin to the meter ground - each should be open (see Figure 5-2 below). Measure the resistance from the Ground pin to the meter ground – this should be grounded to the meter. With the sensor still disconnected, go to the first column of the hidden diagnostics and display the vortex shedding frequency, f. Hold a finger on the four exposed pins on the Signal board. The meter should read electrical noise, 60 Hz for example. If all readings are correct, re-install the vortex sensor wires. 4. Verify all meter configuration and troubleshooting steps previously described. There are many possible causes of this problem, consult factory if necessary. Figure 5-2: Measuring Resistance - Sensor Pin to Meter Ground Troubleshooting and Repair 5-5 June 2007 Electronics Assembly Replacement (All Meters) !WARNING! Before attempting any flowmeter repair, verify that the line is not pressurized. Always remove main power before disassembling any part of the flowmeter. Caution! Electronics boards are electrostatically sensitive. Wear a grounding wrist strap and be sure to observe proper handling precautions for static-sensitive components. 1. Turn off power to the unit. 2. Locate and loosen the small set screw which locks the larger enclosure cover in place. Unscrew the cover to expose the electronics stack. 3. Locate the sensor harnesses which come up from the neck of the flowmeter and attaches to the circuit board. Use small pliers to pull the connector off the circuit board. 4. Locate and loosen the small set screw which locks the smaller enclosure cover in place. Unscrew the cover to expose the field wiring strip. Tag and remove the field wires. 5. Remove the screws that hold the black wiring label in place. Remove the label. 6. Locate the four Phillips head screws which are spaced at 90° around the terminal board. These screws hold the electronics stack in the enclosure. Loosen these screws. Note: These are captive screws. They will stay inside the enclosure. 7. Carefully remove the electronics stack from the opposite side of the enclosure. If the electronics stack will not come out, gently tap the terminal strip with a screwdriver handle. This will loosen the rubber sealing gasket on the other side of the enclosure wall. Be careful that the stack does not hang up on loose sensor harnesses. 8. Repeat steps 1 through 6 in reverse order to install the new electronics stack. Returning Equipment to the Factory Before returning any PanaFlow MV flowmeter to the factory, contact Customer Service. When contacting Customer Service, be sure to have the meter serial number and model code. When requesting further troubleshooting guidance, record the following values first: f, fi, G, and A at no flow and during flow if possible.
